Architecture Implications
Performance Considerations
Architectural Speed Comparison by Approach:
- CDN/Proxy-Based Solutions (Fastest Initial Delivery)
- Weglot, GTranslate, ConveyThis: Translations served from global CDN networks
- Page load impact: Minimal (translations loaded from edge servers)
- Setup time: Under 5 minutes (connect API, instant translation)
- Trade-off: Dependent on external service availability; ongoing costs
- Best for: Sites prioritizing speed of deployment and global delivery
- Local Database Solutions (Balanced Performance)
- WPML, Polylang Pro, TranslatePress: Translations stored in WordPress database
- Page load impact: Low to Moderate (depends on hosting and caching)
- Caching benefits: Can leverage WordPress object caching, page caching plugins
- Database overhead: Additional queries per page (mitigated by caching)
- Best for: Sites wanting control over translations with good hosting
- Multisite Architecture (Optimal Per-Site Performance)
- MultilingualPress, Multisite Language Switcher, RosettaPress: Each language is a separate WordPress site
- Page load impact: Minimal (no translation overhead; standard WordPress performance)
- Trade-off: Higher server resources, longer setup time
- Best for: Enterprise sites where each language can be independently optimized
- Real-Time Widget Translation (Variable Performance)
- Prisna Translate (free), Transposh: JavaScript-based on-page translation
- Page load impact: Low to Moderate (client-side processing)
- Caching: Premium versions offer translation caching
- Trade-off: Initial page render may delay while translation loads
- Best for: Quick multilingual setup without database changes
Caching Capabilities Comparison:
| Solution Type | Server Caching | CDN Caching | Translation Caching | Object Caching |
|---|---|---|---|---|
| Weglot | Via CDN | Yes (built-in) | Yes (automatic) | N/A |
| GTranslate | Via CDN | Yes (built-in) | Yes | N/A |
| ConveyThis | Via CDN | Yes (built-in) | Yes | N/A |
| WPML | Compatible | Compatible | Via caching plugins | Compatible |
| Polylang | Compatible | Compatible | Via caching plugins | Compatible |
| TranslatePress | Compatible | Compatible | Via caching plugins | Compatible |
| Transposh | Custom support | Compatible | Yes (multiple backends) | APC/APCu/Redis/Memcached |
| Prisna Translate | Compatible | N/A | Yes (premium) | N/A |
Database Query Overhead:
- Minimal overhead: Bogo, WP Multilang, Multisite solutions (simple meta/separate tables)
- Low overhead: Polylang (taxonomy-based, efficient queries), BestWebSoft
- Moderate overhead: WPML (comprehensive but heavier), TranslatePress (custom tables), WPGlobus
- Variable overhead: Transposh (depends on caching configuration)
- External/No local overhead: Weglot, GTranslate, ConveyThis (translations not in local database)
Speed Optimization Recommendations by Plugin:
- WPML: Enable built-in caching, use with page caching plugin, disable unused modules
- Polylang: Lightweight by default; compatible with all major caching plugins
- TranslatePress: Use with object caching; translation strings cached after first load
- Weglot: Already optimized via CDN; no local optimization needed
- Transposh: Configure Redis/Memcached for high-traffic sites; enable backend processing
- Multisite plugins: Optimize each site independently using standard WordPress techniques
Data Ownership
- Full ownership: Local database plugins (WPML, Polylang, TranslatePress, WP Multilang, Bogo)
- Shared/external: SaaS solutions store translations on external servers
- Hybrid: Some plugins cache translations locally while using external MT services
Migration Difficulty
- Easiest: Multisite solutions (content already separated), lightweight plugins
- Moderate: WPML, Polylang (established export/import tools)
- Difficult: SaaS solutions (translations stored externally, may require re-translation)
- Complex: WPGlobus (delimiter cleanup required)
Hosting Requirements
- Minimal: Lightweight plugins (Bogo, WP Multilang)
- Standard: Most local database solutions
- Higher: WPML (larger database), TranslatePress (translation records)
- Multisite capable: MultilingualPress, Multisite Language Switcher, RosettaPress
